The European Commission published the State aid simplification package in the Official Journal. The package comprises a Simplified Procedure Notice and a Best Practices Code. The measures are intended to improve the effectiveness, transparency and predictability of State aid procedures. The Simplified Procedure Notice provides for an accelerated procedure and short form decision for certain categories of State aid, and the Best Practices Code sets out guidance on the day to day conduct of State aid proceedings. The Notice and Best Practices Code apply to State aid measures notified from 1 September 2009. The Commission announced that it had adopted the simplification package on 29 April 2009.
